To aZZ whom it may concern:

Be it known that I, LORENZO ZUMrNo, a subject of the King of Italy, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in Combined Baby Chairs and Carts, of which the following is a specification.

My invention relates to baby chairs and go-carts wherein the handle operates in conjunction with the wheels of the go-cart and improved means for locking the said handle in a position where the chair will be elevated upon the wheels; and the objects of my 1nvention are first, to provide improved means for locking the handle of the chair in a position that will support the chair above the ground on which the wheels rest, the same means being also adapted to lock the telescoping handle in an extended position while the chair is elevated upon the wheels; second, to provide improved means for reclining the back of the chair and the foot board thereof; third, to provide a sliding seat for the chair that will move slightly forward and in proportion to the inclination of the back; and fourth, to provide improved means for locking the back of the chair in any one of several inclined positions. 1 accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings and in which- Figure l is a side elevation of the devlce, disclosing one of the bent tubes pivotally mounted on the side of the chair and the wheels rotatably mounted within the lower end of the said tube, the arcuate guide bars secured to the side of chair concentric with the pivot of the tube, the sliding sleeve on the tube and the handle inserted within the tube, the full lines disclosing the position of the wheels when the device is used as a gocart and the dotted lines disclosing the position of the wheels, bent tubes and handle when the device is used as a chair. Fig. 2 is a rear elevation of the chair in the position when being used as a go-cart, disclosing the iJ-shaped handle inserted within the bent tubes, the sleeves slidably mounted on the bent tubes and the staple secured to the sleeves and engaging the arcuate guide bars, also the spring latch on the back of the seat which secures the reclining back and sliding seat in any one of several positions, also the means for releasing the spring latches-which engage the staples on the sleeves, the means for releasing said spring latches, and the means for releasing the spring latch secured to the back of the seat. Fig. 3 is a vertical sectional view of the chair being used as a go-cart and disclosing the back of the said chair in an inclined position and the sliding seat projected slightly forward. Fig. 4: is a broken sectional View of the upper end of one of the tubes disclosing slots on two sides thereof, the sleeve slid-ably mounted thereon and the staple on the said sleeve engaging the arcuate guide bar, and the lug on the said guide bar projecting through the slots in the sleeve and the tube and engaging a depression in the lower end of one end of the U-shaped handle, also the second slot near the top of the tube, which is adapted to engage a spring on the handle for the purpose of preventing the withdrawal of the said handle from the tubes. Fig. 5 is an enlarged broken plan View of one of the arcuate guide bars secured to the side of the chair disclosing the manner in which a staple on the sliding sleeve is engaged by the said bar and manner in which the spring latch engages the staple and the manner in which the lug on the guide bar engages the slot in the sleeve. Fig. 6 is a broken plan view. of one side of the seat disclosing the manner in which the side of the seat is slidably mounted on one of the horizontal bars secured to the sides of the chair. Fig. 7 is a sectional view of Fig. 6 disclosing the manner in which the eyelets secured to the seat engage the horizontal rods which support the said seat, and Fig. 8 is a broken sectional view disclosing the manner in which a spring secured to each end of the U-shaped handle engages the second slot in the upper end of the tube for the purpose of preventing the entire withdrawal of the handle from the said tube.

It is the purpose of my invention to provide an improved baby chair having a reclining back that may be easily converted into a push cart and to provide improved means for locking the reclining back in any one of several positions, and also to provide improved means for locking the bent tubes and the wheels in a position that will support the chair above the ground, the same means also being adapted to lock the. handle in an extended position, also to provide means for unlocking the several parts so as to restore the chair to a position where it will rest on the ground or where the back of the chair may be locked in an upright position.

Referring to the drawings, the numeral 1 is used to designate the sides of a chair having a seat 2 provided with eyelets 3 arranged to engage the horizontal rods 1 secured to each side of the chair 1. A suitable foot board 5 is pivotally mounted on the front end of the seat 2 and is provided with flexible connections 6 between the lower end of the said foot board 5 and the chair 1. A spring latch 7 is secured to the back of the chair and adapted to engage apertures 8 within a bar 9 secured below the approximate center of the seat 2 and to the chair 1. A back 10 is pivotally secured to the back end of the seat 2 by means of pins 12, which engage the slots 13 of the plates 14, which are secured to the sides of the chair 1. A suitable cord 15 is secured to the spring latch 7 and has its upper end secured in a suitable eyelet 16 secured to the upper portion of the back 10. Bent tubes 18 are pivotally secured to plates 19 and have wheels 20 secured to the lower ends thereof. The upper end of each bent tube 18 is provided with a sleeve 21 slidably mounted thereon and having a staple 22 adapted to engage an arcuate guide bar 23 which is secured to the side of the chair 1 and concentric with the pivot of the bent tubes 18. Each arcuate guide bar 23 is provided with a lug 24 adapted to project through a slot 25 in the sleeve 21 which registers with a slot 26 in the tube 18 and engage a depression 27 in each end of the U-shaped handle 28. Each arcuate guide bar 23 is also provided with a spring latch 30 having a beveled lug 31 thereon adapted to engage the staple 22 on the sleeve 21 of the bent tubes 18. Cords 32 are secured to the ends of the spring latches 30 and pass through suitable eyelets secured to the back of the frame portion of the chair 1. The U-shaped handle is also provided with a spring 34 which is arranged to engage a second slot 35 in the top of the bent tubes 18, and thereby prevent the withdrawal of the said handle 28 from the said tubes 18.

The operation is as follows: The handle 28 being in the position shown in the dotted lines of Fig. 1 of the drawings is pulled upward until the springs 34 thereon engage the second slots 35 in the ends of the tubes 18. The engagement of the said spring 34 with the slot 35 will prevent a further withdrawal of the handle 28 and will also bring the recesses 27 of the said handle to a position where they will register with the slots 26 of the tubes 18 and the slots 25 of the sleeves 21. By moving the handle 28 backward to the position disclosed in full lines of Fig. 1 of the drawings, the handle 28, tubes 18 and sleeves 21 will be brought to a position where the lug 24 will project through the registered slots 25 and 26 and engage the depressions 27 of the handle 28. In passing to this position, the staples 22 of the sleeves 21 will pass the beveled lugs 31 on the spring latches 30 so that the said staples 22 cannot pass the said lugs 31 on the return movement of the handle 28 and tubes 18, until the lugs 31 are withdrawn from the path of the staples 22. The lugs 31 may be withdrawn and the handle 28 returned to the position indicated in dotted lines in Fig. 1 of the drawings, by pulling on the cord 32, which will cause the spring latches 30 and the lugs 31 thereon to be withdrawn and thereby allow the return passage of the'staples 22.

In order to recline the back 1001: the seat,

by pulling upward on the cord 15, the spring latch 7 will be withdrawn from the apertures 8 in the horizontal bar 9 which will permit the seat 2 to move forward. By pulling backward on the top of the back 10, the said back 10 will operate as a lever having for its fulcrum the pins 12 operating in the slots 13 of the plates 14, secured to the sides of the chair 1. This will cause the lower portion of the back 10 to move the seat 2 forward and likewise the foot board 5 pivotally mounted on the front end of the said seat. Consequently, the flexible connections 6 swinging in radius will slightly elevate the upper end of the foot board 5 until the said foot board 5 assumes an inclination proportionate to the inclination of the back 10. The spring latch 7 will then engage one of the other apertures 8 in the bar 9 and secure the seat 2 and the back 10 against movement.

It is obvious from the foregoing that I have provided improvedmeans for securing the handle of a baby chair in a position that will lock the handle in an extended position and also the wheels in a position that will elevate the chair 1 thereon. It is also obvious that the handle 28 cannot be depressed while the chair 1 is supported upon the wheels 20 for the reason that the depressions 27 in the said handle 28 will be engaged by the lugs 24: on the arcuate guide bars 23.
